A C2HData PDU with the SUCCESS flag set indicates that the I/O was completed by the controller successfully and means that a subsequent completion response capsule PDU will be ommitted. If we see this flag, fisrt we check that LAST_PDU flag is set as well, and then we complete the request when the data transfer (and data digest verification if its on) is done. While we're at it, reuse a bit of code with nvme_fail_request.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
